Last month Microsoft pushed an update to the Network SxS Stack software in our environment.  They released a version newer than what was listed on this site at the time for production or validation. https://learn.microsoft.com/en-us/azure/virtual-desktop/whats-new-sxs
The Network SxS Stack software is automatically updated from Microsoft and is not controllable by the customer.

It broke the network on all our Windows 365 VM's and AVD vm's if the device rebooted.  The outage lasted for about 2 weeks until Microsoft published the version number we were on 1.02409.29850.  

How can we prevent getting beta versions of the Network stack SxS in our environment?  Is it possible to control which Windows 365 cloud pc's are on the production Network stack vs. validation one as well?
